【摘要】：为了研究唐墓壁画白灰层的特性,本研究以乾陵等7座陕西唐墓壁画的白灰层为研究对象,使用超景深显微镜、扫描电子显微镜、X射线衍射仪、热分析仪和万能材料试验机测试了样品的显微结构、物相、无机物和有机物含量以及力学强度,并探讨了影响白灰层疏松程度、强度的因素。实验结果表明白灰层主要由无机物组成,包括碳酸钙、二氧化硅和锰白云石,平均含量88.71%,有机物平均含量9.33%。白灰层厚度一般为3~5mm,平均孔径约1.77μm,总孔数大致为7920个/mm2,平均抗折强度约0.96MPa。无机物与有机物含量比与疏松程度呈反相关性;疏松程度与强度基本上呈反相关性。小孔径、低含水率、锰白云石可能会增大白灰层的强度。该工作深化了唐墓壁画白灰层的研究,为后期寻找更合适的渗透加固材料、工艺奠定了科学基础。
[Abstract]:In order to study the characteristics of the white ash layer in the murals of the Tang Dynasty tomb, this study took the grey layer of the 7 Shaanxi Tang tombs in the Qianling Mausoleum as the research object, using the ultra depth microscope, scanning electron microscope, X ray diffractometer, thermal analyzer and universal material testing machine to test the microstructure, phase, inorganic and organic content and the mechanical strength of the samples. The results show that the grey layer is mainly composed of inorganic materials, including calcium carbonate, silica and manganese dolomite, with an average content of 88.71%. The average content of 9.33%. is 3~5mm, the average pore size is about 1.77 m, the total number of pores is approximately 7920 /mm2, and the average flexural strength is the average. There is an inverse correlation between the content ratio of 0.96MPa. inorganic substance and organic matter and the degree of porosity, and the degree of porosity and intensity are basically anti correlation. Small pore size, low water content, manganese dolomite may increase the strength of the lime layer. This work deepens the study of the white lime layer in the murals of Tang tomb, and lays the foundation for the later search for more suitable infiltration and reinforcement materials. The basis of science.
